- Is colr-guardrail live?
- Yes — it answered the hub's last check (checked 6d ago). It answered 25% of checks over the last 30 days.
- Is colr-guardrail free to use?
- Not measured yet.
- What tools does colr-guardrail have?
- 6 tools: Evaluate a trade (x402 paid, Tier 2), Evaluate a trade, Check token safety, Simulate a wallet balance, List supported assets, Verify audit trail.
- Is colr-guardrail safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Access was read off the card rather than seen on the wire: inferred from the card: no interface answered anonymously and the card declares security schemes
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
evaluate_trade_paid auth-required never probed
Same as evaluate_trade but gated by an x402 payment. Evaluated as Tier 2 ($25,000 ceiling, 10/25 per-minute rate limits). Call WITHOUT payment_proof to receive a PaymentRequiredOutput challenge; settle on-chain; retry with the proof to receive a full verdict with tier=2. No COLR holdings are required — the on-chain payment is the credential. If the response contains an 'error' key, no verdict was produced — treat as a hard stop.
evaluate_trade auth-required never probed
Pre-trade risk check. Returns allow, warn, or deny, with every reason attached and a tamper-evident audit hash. Checks tier limits, oracle/V4 price source, slippage, market hours, cluster rate limits, and daily loss. If check_token_safety returned severity=danger for the contract, this skill automatically returns deny regardless of other checks. If the response contains an 'error' key, no verdict was produced — treat as a hard stop and do not execute the trade.
check_token_safety auth-required never probed
Honeypot and contract safety check for any ERC-20 token. Returns severity (safe, warn, danger) and the specific risk factors found, using bytecode analysis and a live sell simulation. CRITICAL: when severity=danger, the next evaluate_trade call for the same contract is automatically denied. Use before trading unknown tokens or tokens absent from the official registry. If the response contains an 'error' key, the check failed — do not assume 'safe'.
simulate_balance auth-required never probed
Read-only state-override simulation of an ERC-20 balance after a hypothetical trade. No transaction is sent. If the response contains an 'error' key, the simulation failed.
get_supported_assets auth-required never probed
The official Robinhood Chain asset registry with canonical contract addresses. Resolve a symbol correctly before calling evaluate_trade.
verify_audit_trail auth-required never probed
Recompute every past decision's SHA-256 hash and verify the hash-chain links. Proves no decision was edited, deleted, or reordered. If the response contains an 'error' key, verification could not run.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idf8d416420e9382e2.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/f8d416420e9382e2/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
